args[]
string
Optional. The arguments to pass to the driver. Do not include arguments, such as -libjars
or -Dfoo=bar
, that can be set as job properties, since a collision might occur that causes an incorrect job submission.
jarFileUris[]
string
Optional. Jar file URIs to add to the CLASSPATHs of the Hadoop driver and tasks.
fileUris[]
string
Optional. HCFS (Hadoop Compatible Filesystem) URIs of files to be copied to the working directory of Hadoop drivers and distributed tasks. Useful for naively parallel tasks.
archiveUris[]
string
Optional. HCFS URIs of archives to be extracted in the working directory of Hadoop drivers and tasks. Supported file types: .jar, .tar, .tar.gz, .tgz, or .zip.
properties
map (key: string, value: string)
Optional. A mapping of property names to values, used to configure Hadoop. Properties that conflict with values set by the Dataproc API might be overwritten. Can include properties set in /etc/hadoop/conf/*-site

, and then specify the main class name in this property. driver
can be only one of the following:mainJarFileUri
string
The HCFS URI of the jar file containing the main class. Examples: 'gs://foo-bucket/analytics-binaries/extract-useful-metrics-mr.jar' 'hdfs:/tmp/test-samples/custom-wordcount.jar' 'file:///home/usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar'
mainClass
string
The name of the driver's main class. The jar file containing the class must be in the default CLASSPATH or specified in jarFileUris
.
